“The man pictured was unable to save one of his patients,” wrote Moore. “Though this is a common occurrence in our field of work, the patients we lose are typically old, sick, or some combination of the two. The patient that died was 19 years old, and for him, it was one of those calls we get sometimes that just hits you.”

Moore says he received permission to post the photo on Reddit, which has received over 3,500+ comments. He wanted to share it publicly because he believes it sheds light on what it’s like to be in a life-and-death profession.
